(2) coarse crushing:Sheet material is broken into the coarse-grained material that granularity is no more than 20 millimeters;
(3) primary drying:It is 14~16% by coarse-grained material drying to moisture content;
(4) fine powder:Coarse-grained material after primary drying is subjected to fine powder, the particulate that granularity is no more than 8 millimeters is ground into Material;
(5) redrying and air-flow homogenize:The fine after fine powder is blown into airduct with homogeneous blower fan, filled with air Divide mixing contact, realize moisture, the homogenizing of temperature and be further dried, be 11~12% to moisture content;
(6) collect and store and homogenize:The fine from airduct is collected using cyclonic separation and is sent into One-level feed bin is stored at least 1 hour, continues to homogenize;
(7) transfer storage homogenizes:Fine after being stored through first order feed bin is transferred to second level feed bin storage At least 0.3 hour, continue to homogenize;
(8) pelletizing forming:Pelletizing forming machine is used, the fine after the completion of homogenizing is pressed into biological particles.
Fine after being stored through second level feed bin can be transferred to the storage of third level feed bin again at least by present invention process 0.2 hour, further homogenize.The biological particles prepared are sieved, cooled down, qualified finished product is obtained.
Present invention process at least has advantages below:
(1) present invention by raw materials for production through crushing and drying twice twice, and the drying capacity to material is strong, dry abundant, Particularly airduct is sent directly into through fine powder fine to dry and homogenize, then carry out cyclonic separation, fine is in airduct Interior wind is gradually dried during sending, and can reach the aridity needed for production technology, it is no longer necessary to which occupied ground stacks crushed material Material.Dried fine falls into the storage of first order feed bin after cyclonic separation, and continues during storage to homogenize, then Transfer into follow-up second level feed bin storage, continue to homogenize, according to manufacturing technique requirent, third level feed bin can also be re-fed into More fully homogenize, fully feeding pelletizing forming machine prepares required biological particles to homogeneous afterwards.Biology can be achieved The continuous production of matter particle, greatly improves production efficiency.
(2) because fine is dried fully, in addition since air-flow homogenizes process, until entering pelletizing forming machine Whole process before, fine all in Homogenization, in addition from first order feed bin be transferred to second level feed bin with And continue during being transferred to third level feed bin, material preferably improves homogenizing effect by equably turning, and material is equal Matterization is very abundant so that the superior in quality stabilization of biological particles prepared.In addition in each critical process link to material The control of moisture content, it can be ensured that enter the fine moisture content of pelletizing forming machine in the number range of technological requirement, in life Effective quality control, stabilized product quality and yield are realized during production.
(3) due to raw material is employed coarse powder, drying, fine powder again technique, material is once crushed to compared to existing The mode of production of position, reduces to the loss of equipment, and power consumption is also greatly reduced, power consumption can compared with prior art reduction by 15~ 20%, significantly reduce production cost.In addition set wood chipping equipment that raw material is cut into specification before coarse crushing basically identical Wood chip, more reduces the difficulty and energy consumption of coarse powder.
(4) due to using drying twice, substantially increasing the drying capacity of equipment, all kinds of dry and wet raw materials can be direct plungeed into Production, it is no longer necessary to shine dry raw material in advance, the adaptability of raw material is greatly enhanced.
